How to import txt file in mysql?
Sometimes when we use mysql database, we want to import a txt text document. How to do it? The following article will introduce the method to you, I hope it will be helpful to you.
1. Prepare data and create a test table
1. Prepare the txt text document that needs to be imported. The path is: c :/data.txt.
Use the Tab key to separate each item. If the field is NULL, use /N to indicate it.
2. Create a new database and a table. The fields designed in the table need to correspond to the number of columns in the imported text document.
Example: Create a table representing student information for testing. The fields include id, name, age, city, and salary. Id and name cannot be empty.
create table person( id int not null auto_increment, name varchar(40) not null, city varchar(20), salary int, primary key(id) )engine=innodb charset=gb2312;

load data local infile “c:/data.txt” into table person(name,age,city,salary);
The screenshot of the imported data is as follows:

3. Export data
Now export this table to a text file: c:/data_out.txt.
select name,age,city,salary into outfile “c:/data_out.txt” lines terminated by “/r/n” from person;
The screenshot of the exported data is as follows:
